HUMIDIFIER.

Specification of Letters Patent.

Patented July 23, 1918.

Application filed June 9, 1916. Serial No. 102,689.

To all whom it may concern:

Be it known that we, VERN SLATER and LEONIDAS D. Wns'r, citizens of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Humidifiers; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in humidifying devices and the main object thereof is to provide a comparatively simple yet highly efficient apparatus of this class which may be inexpensively manufactured and marketed. Other objects are to construct the device in a number of uniquely designed sections which not only render it easy to manufacture, but serve important functions when the device is in use.

*With the foregoing general objects in view, the invention resides in certain novel features of construction and in unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawing which constitutes a part of this application and in which:

Figure 1 is a view, partly in elevation and partly in section, of a portable appliance provided with the improved device;

Fig. 2 is an enlarged vertical sectional view of the improved portion thereof;

Figs. 3 and 4: are horizontal sectional views as seen on the planes of the lines 3-3 and 44 of Fig. 2; and,

Fig. 5 is a top plan view.

In specifically describing the structure shown in the drawings above briefly described, similar characters will be employed to designate corresponding parts throughout the several views and reference will be herein made .to the numerous elements by their respective indices. To this end the numeral 1 designates an upright cylindrical casingwhich rises from a suitable base 2,

"said casing having an openwork top 3 through which air is permitted to enter said casing and also having an air outlet l, an electrically driven fan 5 being disposed in the casing for drawing air into the upper and secured in place by screws 7 or other suitable means, the upper edge of said ring being turned downwardly and inwardly to provide a frusto-cone-shapcd flange 8 which is preferably perforated as shown at 9. Inverted L-shaped brackets 10 are secured to and rise from the ring 6, said brackets supporting thereon a horizontally disposed disk 11 perforated at 12 and having a central internally threaded boss 13.

A water pan 14 is provided at its center with a tube 15 which extends above and below the bottom of said pan, the lower end of said tube resting onthe disk 11 in vertical alinement with the boss 13. A sheet of suitable fabric or other absorbent material 16 is disposed over the pan .1 1 resting on the beaded edge thereof, the edge of this sheet being stitched, cemented or otherwise secured to an apron 17 of similar material which depends around the upper end of the casing l in spaced relation thereto. A cylindrical sleeve 18 of woven wire or the like is disposed in contact withthe inner side of the apron 17 to retain the same in shape and a lining 19 of absorbent material is preferably sccured in said sleeve, the lower edges of the parts 17 and 19 being secured together, as shown clearly in Fig. 2, to prevent dislocation of the sleeve 18.

A cylindrical guard sleeve 20 surrounds and is spaced outwardly from the apron 17, said sleeve being constructed of metal and having a top 21 of wire gauze or the like to permit the entrance of air, said top having at its center a central opening and being secured at the edge of said opening to a ring 22 from which arms 23 radiate, the outer vice in operative relation.

equipped with abase28 in the form of an tube and boss 13 whereby a vertical screw 27 may be passeddownwardly through these alining partsand threaded into said boss to retain all of the sections of the de- Reservoir is annular vertical flange which depends from its bottom, said base serving to depress the centerof the sheet 16 into the pan 14;, water being siip plied to' said sheet and pan "from r V the reservoir 25 through a slit tube 29 whose slits may be exposed or covered to the desired extent by means of'a suitable screw cap 30. The tube2 9 delivers into the flange or base 28 and to permit the liquid to readily leavesaid flange to partly fill the portion of the pan 14L surrounding the same, the lower edge ofsaid, flange is notched as indicated at3l.; 1 U By-constructing the improved ClGVlCG 1n themanner shown and described it willbe a highlyleflicient air humidifier, it being, ob-

V viousfrom Fig. 2 that the operation of the fan 5 will draw. air into the casing between the lining 19 and said casing, while, owing to the open Weaveof sa1d llnmggand the.

apron 17, a considerable amount of air will be drawn through these parts, and finally on account of-the reticulartop' 21 of the guard; sleeve 20, air will also be drawn through the portion of the sheet 16 which extends be- 7 yond the edge of the pan l l Allof these absorbent parts will be readily moistened by the water from the pan 14 and thus the air traveling in the manner setzfor'th Will be effectively humidified, this air belng expelled from thev casing 1 through the outlet 2 at from whichit may be conducted to any suitable point. 4:0
